This should be independent of the EV system. That is to say, Pokémon should have higher stats thanks to this feature, as implied by Ishihara and Masuda. But it might be better to have the trainer be the deciding factor of the stat boosts; different trainers would have different qualities that would make their Pokémon stronger in specific stats.*Stats Boosts: As the Bond Level increases, the Pokemon give each other small stat boosts. I was thinking at 25%, 50%, and 75% they give their partners stat bonuses, based on their third, second, and then first strongest stat, perhaps calculated based on their Base Stats.
Some Pokémon should be able to bond more effectively than others. Those Pokémon would benefit from more substantial stat boosts. I also think that the bond between two Pokémon should allow them to teach each other compatible moves.
I am not sure about this one. For one thing, the use should be limited to once per battle; what happens after the battle is irrelevant. But even then, the combination of support abilities and Bond Strike might be going overboard.*Bond Strike: When Pokemon reach 100%, their Bond is established and they gain access to a Bond Strike Bar...it fills up whenever one of them is in battle, and, when filled, the trainer can initiate a Bond Strike, which allows them to choose an attack of the Pokemon currently out, then an attack of their Bond partner. The first one attacks when their turn occurs, then they switch in the same turn to the other Pokemon, who attacks once more with their attack. The Bond Strike Bar would empty after each match, and wouldn't fill too fast, so it would be sort of a "last-resort" option when facing strong bosses. Of course, the CPU could do it too, with some of the tougher trainers strategically bonding Pokemon to use against you.
When they max out the Bond Bar, I was thinking they could perhaps gain a special "boost" to their stats as long as the Bond Bar is maxed out. Nothing extreme, but a few points added to each stat. Of course, this could be disabled for competitive play.Any new battle structure should not be an optional feature. Look at the Wonder Launcher: How many people actually use it?In Player vs. Player matches, you can play classic, or play with the Bond System on, adding a new realm of strategy as players will want to find good combinations based on stat bonuses and support abilities.
